Initial support for custom keymaps per widget group

This adds widget-group level, configurable keymaps. This means, for each widget group (e.g. Manipulator Widgets, Camera Widgets, etc), 6 keymap entries are added:
* Widget Activate (action-mouse down)
* Widget Activate (actually deactivate - action-mouse up)
* Widget Tweak (mouse move)
* Widget Tweak Cancel (RMB)
* Widget Tweak Cancel (esc)
* Widget Select (only for selectable widgets - select-mouse)

This might be useful e.g. to set certain widgets to activate on tweak event only to resove conflicts (see manipulator vs. selection with LMB-select conflict), and for things like setting a widget values using shortcuts (not yet possible, but easy to add now).
Further, this greatly improves the IMHO current ugliest part of the widget backend, the event system part/hack :P o/

One remaining issue is that the keymap items only appear using search, they are not displayed in the keymap editor list by default (didn't investigate yet).

Old functionality was ported over to new system, everything should work fine still.
